Abstract
The utility model relates to a ceramic base for a quartz crystal resonator. The ceramic base comprises a main body (1). Inner part printing terminals (11, 11`) and outer part printing terminals (12, 12`) are correspondingly arranged at the two sides of the plate face and the bottom face of the main body(1), printing communication belts (13, 13`) are arranged at the side faces, and the inner part printing terminals (11, 11`) is electrically connected with the outer part printing terminals (12, 12`) by the printing communication belts (13, 13`) at the side faces. The ceramic base has the technical effects of simple structure, small volume, low cost, strong impact resisting property, simple production processing technology and the like.
Description
Technical field
A kind of base of ceramic that the utility model relates to refers in particular to a kind of quartz-crystal resonator base of ceramic.
Background technology
The traditional quartz-crystal resonator of China is mainly produced by labour-intensive, and its efficient is low, profit is meagre and production technology does not have substantive breakthroughs, and its size is bigger, is mainly used on the low precision electronic products such as toy for children, game machine, television set.And be used for ask for something on the high accuracy electronic products such as mobile phone, notebook computer, satellite communication device take up room little can surface-pasted crystal resonator, the production core technology of oscillator, filter base of ceramic grasps hand abroad always.The known quartz-crystal resonator that mounts, the technology that its base of ceramic adopts lamination, burns altogether, has the complex structure shortcoming, and, make that the production cost of base of ceramic is high always, and output also is subjected to the restriction of technology, equipment each side because the inconsistent meeting of percent of firing shrinkage of pottery and metal paste causes the problem of bottom slab warping distortion, can not be satisfied with the growing market demand far away, therefore, how to address the above problem, become problem demanding prompt solution.
The utility model content
The technical problems to be solved in the utility model provide a kind of simple in structure, volume is little, cost is low, impact resistance is strong, the simple a kind of quartz-crystal resonator base of ceramic of production and processing technology.
For solving the problems of the technologies described above, a kind of quartz-crystal resonator base of ceramic of the present utility model, comprise body, the both sides of entity plate face and bottom surface are provided with corresponding inside printing terminal and outside printing terminal, side are provided with printing and are communicated with band, inner printing terminal and outsidely print the printing of terminal by the side and be communicated with charged the connection.
Above-mentioned a kind of quartz-crystal resonator base of ceramic, the thickness of slab of described ceramic bottom laminate is not less than 0.6mm, can carry out stable vibration to guarantee wafer, and absorbs the external impact that is applied on the wafer to a certain extent and protect wafer.
Above-mentioned a kind of quartz-crystal resonator base of ceramic, the thickness of described inner printing terminal is not less than 50 μ m, guarantees to make wafer play effective vibration.
Above-mentioned a kind of quartz-crystal resonator base of ceramic, described inner printing terminal, outside printing terminal and printing are communicated with band and are argent.
After the utility model adopts said structure, by adopting plane ceramic bottom flaggy to simplify the structure, on the ceramic bottom flaggy, form inner printing terminal and outside printing terminal and printing by direct type metal slurry and be communicated with band, need not to consider the pottery owing to burning altogether and the inconsistent problem that causes bottom slab warping distortion of percent of firing shrinkage of metal, as long as print thickness is guaranteed, when sintering, can ignore pottery and generally the flexural deformation of the crystal oscillator ceramic packaging that cause inconsistent with the thermal expansion metal coefficient.
Adopt the quartz wafer of sheet type quartz crystal resonator of the present utility model to realize that volume is little and guaranteed operational quality with the cramped construction that electrode also is connected; simplified production technology simultaneously and reduced production costs; adapted to the requirement of electronic devices and components to miniaturization, large-scale development; can realize the technique effect that the automation surface mounts, be specially adapted to the high accuracy electrical equipment use that mobile phone, notebook computer etc. take up room little.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but does not constitute any restriction of the present utility model.

Among the figure: 1 is the ceramic bottom laminate, and 11,11 ' is inner printing terminal, and 12,12 ' is outside printing terminal, and 13,13 ' for printing is communicated with band, and 2 is ceramic cap, and 21 is groove, and 3 is wafer.
Embodiment
As Figure 1-3, a kind of quartz-crystal resonator base of ceramic, comprise body 1, the both sides of body 1 plate face and bottom surface be provided with corresponding inside printing terminal 11,11 ' and outside printing terminal 12,12 ', side be provided with printing and be communicated with and be with 13,13 ', inner printing terminal 11,11 ' and outside printing terminal 12,12 ' printing by the side be communicated with and be with 13,13 ' to be electrically connected; Bottom plate 1 thickness of slab is 0.6mm; Inner printing terminal 11,11 ' thickness are 50 μ m; Inner printing terminal 11, inner printing terminal 11 ', outside printing terminal 12, outside printing terminal 12 ' and printing are communicated with is with 13,13 ' to be argent.
As shown in Figure 4, the utility model is when concrete the use, and wafer 3 is bonded on the inner printing terminal 11,11 ' by conducting resinl; Ceramic cap 2 is provided with the groove 21 of wafer 3, and ceramic cap 2 and ceramic bottom laminate 1 are tightly connected by low molten glass seal layer.
Above-described embodiment only is a preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make the adjustment and the improvement of some structures, these also should be considered as belonging to protection range of the present utility model.
